endtlo f. heddle'supportingcbard6i a a V x. The foregoing arrangement is suckr tliatnthee heddle supporting bars IB are normally held against longitudinal movement in the frame but upon the removal of one of the locking plates 19, the heddle supporting bar I6, which is normally retained by said plate 19, may be slid lengthwise for the purpose of removing the same and thereby permitting the heddles to be removed from the frame.

The heddles 25 are made of thin flat strips of metal, with their end portions 26 shaped substantially as shown in the Lackey patents hereinbefore'referred to, that is to say, each end portion 26 of each heddle 25 is provided with a recess 21 in which an inwardly extending enlarged bead portion I! of a heddle supporting bar i6 is positioned, and the shank 28 on each side of said recess in the end portion of the heddle extends substantially parallel for a short dis tance on each side of the bead portion I! of the heddle supporting bar 16, thence extending inwardly toward each other to hold the same in engagement with the enlarged bead portion I! of the bar l6.

Each of the heddles 25 is of course provided with a central warp eye 29 of any preferred conformation.

Each of the heddles 25 is also provided, near each end, with a slot 38. Bars 3! extend through the slots 30 of the heddles. Said bars 3! extend from end to end in the frames and are restrained against longitudinal movement therein by abutting against the side struts I I. The bars 3! serve to prevent any of the individual heddles 25, in the event of the same becoming unduly stressed, from becoming detached from the heddle supporting bars l6, and also to maintain the heddles 25 in orderly arrangement whenever the same are removed from the heddle frame for any purpose. a

By the foregoing arrangement, there is provided a heddle frame, and heddles mounted therein, which can be readily utilized in those installations which employ automatic drawingin machines for entering'the warp through the harness, it being noted that there are no obstructions to the free passage of the heddles from one end of the frame to the other.

The provision of the bars 3| serves to stabilize the heddles 25 in the frame and prevents the individual heddles from becoming detached from the heddle supporting bar. The heddles may be readily removed from the heddle frame for any desired purpose, and the orderly arrangement of the same, when so removed, may be maintained by means of the bars 3|.
